Description
Technical field
The present invention relates to a kind of sheet metal component surface thermosetting powder coatings, and method is mixed, and belongs to dusty spray mixing
Mixing plant technical field.
Background technology
Thermosetting powder coating is a kind of emerging new material, and existing paint can be substituted on metal by being baked, than
Existing paint is more environmentally-friendly and safe.The manufacture craft of thermohardening lacquer powder is 1, first raw material are mixed evenly；
2, mixed raw material heated, be squeezed into sheet body, cooling, be crushed to bulk；3, by block-like material body, it is put into flour mill mill
Carefully, have multiple tracks screening process after levigate, powder it is special it is thin, thin, slightly respectively enter in corresponding equipment；4, reach certain fineness
Powder adds some additives according to actual needs（Such as pearl powder）.It needs to use when producing thermosetting powder coating mixed
Material machine mixes raw material, and the mixed effect of general mixing arrangement is bad, inefficient, and general mixing arrangement cannot
It realizes the charging of automatic ration in proportion, influence is produced on production efficiency.
The powder mixing device as disclosed in Patent No. 201710497890.5, including the first blending tank and the second mixing
Tank, the material outlet of first blending tank are connected to the material inlet of second blending tank；First blending tank includes
Tank body and the first electric rotating machine, the bottom of first blending tank are installed with the first electric rotating machine, first electric rotating machine by
Elevating lever connects lifting gear, and the shaft of first electric rotating machine stretches into the inside of first blending tank, this kind of thermosetting property
Coating powder mixing arrangement stirring and mixing effect is more preferable, and the working efficiency of mixing arrangement is improved, and improves thermohardening lacquer
Production efficiency, the noise that generates when silencer cover can effectively reduce motor work reduces pollution, improves the work of operative employee
Make environment, while being stirred, scrapes hairbrush and the inner wall of tank body and transport tube is scraped, avoid raw material and be adhered to
Waste, is also convenient for the cleaning to material tube after use caused by inner wall；The powder mixing device is simply by stirring
Mode mixes, and can have blind area, mixing effect is poor.
For another example in the powder mixing device of Patent No. 201710197046.0 and method, the load powder of multichannel powder to be mixed
Air-flow enters the inner cavity of the lid by the multiple admission lines being set on lid respectively, while driving the lid inner cavity
In vortex leaf rotated, i.e., treat mixed-powder and mixed using carrying powder direct hybrid mode of supplying gas.Specifically, using
Vortex leaf is mixed, and avoids using more connectors parts, reduces the possibility that turbulent flow occurs when multichannel air-flow collects, Jin Erzeng
Mixing quality is added；Powder air-flow will be carried by, which only needing, is respectively connected to admission line, and it is mixed that powder can be completed in this powder mixing device
It closes, saves the time and efforts manually mixed, save resource, reduce cost；Powder mixing device may be mounted at cladding
End, powder can directly be connect with melting-painting nozzle by outlet pipe after mixing, are carried out laser melting coating, avoided first mixing again defeated
Various destabilizing factors during sending cause uniformity to be deteriorated, and improve cladding quality；Although although the stirring phase of vortex leaf
It is more abundant than common stirring, but can not be sufficiently mixed under more powder accumulation state since weight is excessive.
Invention content
The technical problem to be solved in the invention is in view of the above shortcomings of the prior art, and to provide a kind of sheet metal component surface
Method is mixed with thermosetting powder coating.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of sheet metal component surface thermosetting powder coating mixing method, includes the following steps：Step 1, to outer barrel introversion
The powder of falling pigment and other additives, account for the 2/3 of outer barrel volume；Step 2, the rotation of opening of rotary shaft and helical blade, drive rod
Polygon idler wheel is driven to be rolled on flat base, outer barrel rotates on polygon idler wheel, and generates vibration and shake；Step
Rapid 3, the powder of outer barrel bottom and the powder inside infundibular body move up under the influence of the rotation of helical blade, helical blade
Rotation also the powder inside infundibular body is stirred；Step 4, after a large amount of powder enters infundibular body, porous mistake is spread over
On filtering layer, coordinating the vibration and shake of outer barrel entirety, powder is filtered from the through-hole of porous filtering layer, and is spread to outer barrel inner bottom surface,
Powder is mutually mixed in dropping process；Step 5, powder reaches the cycle that next round is waited in outer barrel again.
The rotation direction of scheme as a further preference, the shaft and helical blade is opposite.
Scheme as a further preference, in step 2, the rotating speed of the shaft is 4 seconds/circle.
Scheme as a further preference, in step 2, the rotating speed of the helical blade is 2 seconds/circle.
Scheme as a further preference, the angle formed between the side wall and outer barrel bottom of the infundibular body is 45 °-
75°。
Compared with prior art, method is mixed in a kind of sheet metal component surface of the invention thermosetting powder coating, more
Rolling of the side shape idler wheel on flat base drives outer barrel to generate high-frequency vibration, and the rotation of helical blade can be by outer barrel bottom
Powder in portion and infundibular body is brought up, until spreading on porous filtering layer, under high-frequency vibration, powder passes through porous
Filter layer differentiation filter scatters outer barrel bottom again, and powder is during the rotation of helical blade rises and from porous mistake
Filtering layer differentiation can be mixed adequately during scattering.
